Further, in the portion where the second vertical rib 21 is provided, both the outer layer body 2 and the inner layer body 3 are recessed in a concave rib shape. The lengths of these eight second vertical ribs 21 are the same, and their vertical positions are also the same.

The second vertical ribs 21 are provided at intervals in the vertical direction with respect to the first vertical ribs 20. That is, a space is provided in the vertical direction between the lower end of the first vertical rib 20 and the upper end of the second vertical rib 21. As a result, as shown in FIG. 2, the outer peripheral surface of the shoulder portion 12a of the body portion 12 extends over the entire circumference through between the lower end of the first vertical rib 20 and the upper end of the second vertical rib 21. At the same time, an annular region A formed on a flat surface (conical surface) on which the first vertical rib 20 and the second vertical rib 21 are not provided is provided.

As shown in FIG. 1, each of the second vertical ribs 21 is provided so as to be offset in the circumferential direction with respect to the extension line of the first vertical rib 20 provided above the second vertical ribs 21. That is, each of the second vertical ribs 21 is provided so as to be displaced in the circumferential direction with respect to the first vertical rib 20. In the case shown in the drawing, the two second vertical ribs 21 on one side of the reference line L are arranged symmetrically with the extension line of the first vertical rib 20 above the reference line L, and similarly, the reference line L is arranged. The two second vertical ribs 21 on the other side of the above are arranged symmetrically with an extension line of the first vertical rib 20 above the ribs 21.

In the laminated peeling container 1 having such a configuration, since the first vertical rib 20 and the second vertical rib 21 are provided on the body portion 12, the inner layer body 3 is subjected to the initial peeling treatment of the inner layer body 3. As shown in FIG. 5, in the portion of the body portion 12 where the first vertical rib 20 and the second vertical rib 21 are provided, the outer layer 2 and the inner layer are formed while most of the above is in close contact with the inner surface of the outer layer 2. A gap G can be formed between the outer layer body 2 and the inner layer body 3 without bringing the 3 into close contact with each other. That is, in the laminated peeling container 1 subjected to the initial peeling treatment, a gap G is provided between the outer layer 2 and the inner layer 3 in the portion of the body 12 where the first vertical rib 20 and the second vertical rib 21 are provided. It will be of the provided configuration.

For example, after the laminated peeling container 1 is formed by blow molding, the air inside the inner layer 3 is sucked out from the mouth portion 11, or air is blown into the space between the outer layer 2 and the inner layer 3 from the outside air introduction hole 14. Then, the inner layer body 3 is once separated from the outer layer body 2, and then air is supplied from the mouth portion 11 to the inside of the inner layer body 3 to return the inner layer body 3 to the original state in which the inner layer body 3 is laminated on the outer layer body 2. The initial peeling treatment of the inner layer body 3 can be performed. In this initial peeling treatment, the inner layer 3 once peeled from the outer layer 2 is re-stacked on the inner surface of the outer layer 2, and at that time, the first vertical ribs 20 and the second ribs 20 of the outer layer 2 are relaminated. A positional shift occurs between the portion provided with the vertical rib 21 and the portion provided with the first vertical rib 20 and the second vertical rib 21 of the inner layer body 3, whereby the inner layer body 3 becomes the outer layer body 2. It becomes difficult to adhere to the inner surface. As a result, a gap G as shown in FIG. 5 is formed between the outer layer body 2 and the inner layer body 3. Further, since the first vertical rib 20 and the second vertical rib 21 are provided at intervals in the vertical direction, the first vertical rib 20 and the second vertical rib 21 of the body portion 12 are provided. Since the shape or structure of the portion becomes complicated, it becomes more difficult for the inner layer body 3 to come into close contact with the outer layer body 2 in the portion. As a result, a gap G can be reliably generated in the portion of the body portion 12 where the first vertical rib 20 and the second vertical rib 21 are provided.

Further, by providing the second vertical rib 21 so as to be displaced in the circumferential direction with respect to the extension line of the first vertical rib 20, in the portion where the first vertical rib 20 and the second vertical rib 21 are provided. The shape or configuration of the body portion 12 can be further complicated. As a result, in the initial peeling process, it is made more difficult for the inner layer body 3 to come into close contact with the outer layer body 2, and a gap is more reliably provided in the portion of the body portion 12 where the first vertical rib 20 and the second vertical rib 21 are provided. G can be generated.

By providing the first vertical rib 20 and the second vertical rib 21 on the body portion 12 in this way, after the initial peeling treatment of the inner layer body 3, the first vertical rib 20 and the second vertical rib 21 of the body portion 12 are provided. Since a gap G can be generated in the portion provided with and, the inner layer body 3 can be easily peeled from the outer layer body 2 in the portion. Therefore, after the outer layer 2 is squeezed and the contents are poured out, the inner layer 3 can be surely peeled off from the outer layer 2 when the outer layer 2 is restored to its original shape. Further, the gap G formed in the portion of the body 12 where the first vertical rib 20 and the second vertical rib 21 are provided forms an outside air introduction path from the outside air introduction hole 14 toward the bottom 13. become. Therefore, when the outer layer 2 is restored to its original shape after the contents are poured out, the outside air sucked between the outer layer 2 and the inner layer 3 from the outside air introduction hole 14 is taken into the body 12. It can be reliably flowed to the bottom 13 side through the outside air introduction path formed by the gap G formed in the portion where the first vertical rib 20 and the second vertical rib 21 are provided. Therefore, when the outer layer 2 is restored to its original shape after the contents are poured out, the inner layer 3 is surely peeled off from the outer layer 2 from the bottom 13 side toward the body 12 side. Therefore, it is possible to reliably prevent the outside air from being introduced into the accommodation space S of the inner layer body 3. Further, by easily peeling the inner layer body 3 from the outer layer body 2, the squeeze outer layer body 2 can be surely returned to the original shape, and the deformation of the outer layer body 2 can be prevented.

Further, even in the configuration in which the neck ring 15 is provided at the lower end of the mouth portion 11 as in the present embodiment, the notch portion 15a is provided in the portion directly below the outside air introduction hole 14 of the neck ring 15 to cut the neck ring 15. By facilitating the inner layer 3 from the outer layer 2 at the portion where the notch 15a is provided, the outside air can be surely introduced from the outside air introduction hole 14 into the gap G of the first vertical rib 20. In the present embodiment, since a pair of first vertical ribs 20 are provided on both sides below the notch portion 15a, the first vertical ribs 20 and the second vertical ribs 21 are provided from the notch portion 15a, respectively. A gap extending toward the surface is created between the outer layer 2 and the inner layer 3, and when the outer layer 2 is restored to its original shape, it is sucked from the outside air introduction hole 14 between the outer layer 2 and the inner layer 3. The removed outside air can be reliably flowed to the bottom 13 side through the outside air introduction path formed by the gap G between the first vertical rib 20 and the second vertical rib 21.

Indicates the case.

Similar to the first vertical rib 20 and the second vertical rib 21, these third vertical ribs 22 are also formed as concave ribs that extend in the vertical direction and are recessed toward the inside of the container, respectively. In the portion where the rib 22 is provided, both the outer layer body 2 and the inner layer body 3 are recessed in a concave rib shape. The lengths of these eight second vertical ribs 21 are the same, and the positions in the vertical direction are also the same. Further, each of the third vertical ribs 22 is arranged on an extension line of the second vertical rib 21 provided above the third vertical ribs 22.

In the laminated peeling container 1 provided with the third vertical rib 22, the outer peripheral surface of the shoulder portion 12a of the body portion 12 passes between the lower end of the first vertical rib 20 and the upper end of the second vertical rib 21 and covers the entire circumference. In addition to the annular region A1 formed on a flat surface (conical surface) on which the first vertical rib 20 and the second vertical rib 21 are not provided, the lower end of the second vertical rib 21 and the third vertical rib 21 are formed. An annular region A2 formed on a flat surface (conical surface) on which the second vertical rib 21 and the third vertical rib 22 are not provided is provided while extending over the entire circumference through the space between the rib 22 and the upper end. Will be.

Although details are not shown, in the laminated peeling container 1 provided with the third vertical rib 22 in addition to the first vertical rib 20 and the second vertical rib 21 on the body portion 12, the initial peeling treatment of the inner layer body 3 is performed. Then, while most of the inner layer body 3 is brought into close contact with the inner surface of the outer layer body 2, the outer layer body 2 is provided in the portion of the body portion 12 where the first vertical rib 20, the second vertical rib 21, and the third vertical rib 22 are provided. A gap G can be created between the inner layer 3 and the inner layer 3. That is, the laminated peeling container 1 provided with the first vertical rib 20, the second vertical rib 21, and the third vertical rib 22 on the body portion 12 undergoes the initial peeling process, so that the first vertical rib 20, the second vertical rib 21 is provided. In addition, a gap G is provided between the outer layer body 2 and the inner layer body 3 in the portion where the third vertical rib 22 is provided.

In this way, by providing the third vertical rib 22 in addition to the first vertical rib 20 and the second vertical rib 21, the first vertical rib 20, the second vertical rib 21, and the third vertical rib 22 can be formed. The shape or configuration of the body portion 12 in the provided portion can be further complicated. Therefore, in the initial peeling process, it is made more difficult for the inner layer body 3 to come into close contact with the outer layer body 2, and the first vertical rib 20, the second vertical rib 21, and the third vertical rib 22 of the body portion 12 are provided. Further, the gap G can be surely generated. As a result, when the outer layer 2 is restored to its original shape after the contents are poured out, the outside air sucked from the outside air introduction hole 14 between the outer layer 2 and the inner layer 3 is removed from the first vertical rib 20. , When the outer layer 2 is restored to its original shape by surely flowing into the bottom 13 side through the outside air introduction path formed by the gap G between the second vertical rib 21 and the third vertical rib 33, the inner layer body 3 can be surely peeled off from the outer layer 2 from the side of the bottom portion 13 toward the side of the body portion 12.

Further, the first vertical rib 20, the second vertical rib 21, and the third vertical rib 22 are not limited to the concave rib shape that is recessed toward the inside of the container, but are formed into a convex rib shape that protrudes toward the outside of the container. You may. In this case, the first vertical rib 20 and the third vertical rib 22 have a concave rib shape, and only the second vertical rib 21 has a convex rib shape, or the first vertical rib 20, the second vertical rib 21, and the third vertical rib 21 have a convex rib shape. As the rib 22, the concave rib shape and the convex rib shape are alternately arranged, and the first vertical rib 20, the second vertical rib 21, and the third vertical rib 22 are each concave rib shape. It is also possible to have a configuration in which a thing and a thing having a convex rib shape are mixed and provided. Thereby, the shape or configuration of the body portion 12 in the portion where the first vertical rib 20, the second vertical rib 21, and the third vertical rib 22 are provided can be further complicated.
